National Blue Collar Day is observed in the USA on December 8 every year to honor the contributions of blue-collar workers who perform essential manual labor. The day was established by Todd Sohn in 2019 to recognize individuals in various fields such as construction, manufacturing, and maintenance, who often do not receive adequate credit for their hard work. Traditionally, blue-collar workers are associated with physical labor and typically do not require a college education, with many skills learned through on-the-job training. The term "blue-collar" originated in the 1920s, referring to the blue uniforms worn by manual laborers, contrasting with the white shirts of office workers. On this day, people are encouraged to express their appreciation for blue-collar workers through social media, greeting cards, or small gifts, emphasizing that everyone deserves respect regardless of their occupation.
